Answer:

Weight=20.41kg

Explanation:

[tex]F=ma[/tex]

Force on one leg is 50N. Assuming the force exerted by the chair's weight is equally distributed on the 4 legs, then

Total Force on earth by chair=4F=4*50=200N

F=200N

Acceleration, [tex]a=9.8 m/s^2[/tex]

Therefore:-

[tex]m=\frac{F}{a}\\m=\frac{200}{9.8}\\m=20.41kg[/tex]

Answer:

W = 200 [N]

Explanation:

The normal force is the reaction of the surface, of the weight of a body, in this way the weight and the reaction are equal forces but in opposite directions.

N = W

where:

N = normal force [Newtons]

W = weight [Newtons]

So if the chair has four legs, its weight is distributed on all four legs, in this way we have.

4*(50) = W

W = 200 [N]
